This application is applicable to the field of communications technologies, and provides a method and a device for preventing data misdeletion, a storage medium, and a program product. The method includes: Each of an IoT terminal and a user terminal is provided with a misdeletion prevention switch; and when a user opens the misdeletion prevention switch of the user terminal, the misdeletion prevention switch of the IoT terminal is synchronously opened, and when a server obtains a deletion request generated by the server, the server does not respond to the deletion request. In this way, the misdeletion prevention switch of the IoT terminal is in an opened state, data of the IoT terminal stored in the server is not deleted, and data of the IoT terminal stored in the IoT terminal is also not deleted, so that related data of the IoT terminal can be prevented from being mistakenly deleted, to prevent the IoT terminal from being mistakenly deleted from an Internet of Things that the IoT terminal has accessed. This can improve reliability of an IoT system.

A method for performing biometric recognition in a system in which biometric information is distributed and stored in a plurality of databases includes extracting biometric information of a user, generating a plurality of biometric information segments by dividing the extracted biometric information, calculating distances between pre-stored biometric information template segments for each of the plurality of databases and a corresponding one of the plurality of biometric information segments, and detecting a biometric information template matching the biometric information by using the calculated distances.

Systems and techniques for sharing media may utilize or implement a server receiving a media share request from a first device associated with a first user, the media share request including metadata pertaining to a media, retrieving a set of candidate media and fine tuning the set of candidate media to determine a selected candidate media, and transmitting metadata associated with the selected candidate media to a second device associated with a second user or transmitting a set of application program interface (API) calls to the second device.

An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation which may be efficiently processed to determine correspondence. Applications of the interface and system include a VCR, medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

Data is received describing a local model of a first device generated by the first device based on sensor readings at the first device and a global model is updated that is hosted remote from the first device based on the local model and modeling devices in a plurality of different asset taxonomies. A particular operating state affecting one or more of a set of devices deployed in a particular machine-to-machine network is detected and the particular machine-to-machine network is automatically reconfigured based on the global model.

This application discloses a session management method, a network device, and a communications system. According to embodiments of the present invention, an intermediate session management entity is selected based on UE location information and PDU session requirement information. In this way, an intermediate session management entity near UE can provide a service for a PDU session, and a delay of data transmission is reduced. In addition, the intermediate session management entity selects a user plane entity based on the UE location information and the PDU requirement information, and the intermediate session management entity is responsible for managing user plane entities within a specified area, and does not need to manage user plane entities in the entire PDU session, thereby reducing management complexity.

Disclosed in the embodiments of the present disclose are a method and device for sending information. A particular embodiment of the method comprises: acquiring user input information input to a user terminal; determining, from a target expression image set, at least one expression image to be sent to the user terminal and matching the user input information, and a presentation order of the at least one expression image; and sending presentation information to the user terminal in response to determining that, during a historical time period, the user terminal presents the at least one expression image according to the presentation order less than or equal to a target number of times, wherein the presentation information is for instructing the user terminal to present the at least one expression image according to the presentation order.

An access request scheduling method includes determining a city and a city operator corresponding to an access source IP segment; selecting, from cloud delivery nodes of the city operator, a preferred node of the access source IP segment; determining a mapping relationship between the access source IP segment and an IP of the preferred node; and issuing the mapping relationship to scheduling agent modules of the cloud delivery nodes in a network.

Disclosed is a method for transmitting and receiving a physical protocol data unit (PPDU) in a wireless communication system. A terminal receives a preamble of the PPDU from an access point (AP). The preamble includes a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field, wherein the EHT-SIG field may be configured with at least one content channel on a frequency axis. Here, the number of the at least one content channel may be recognized on the basis of the U-SIG field. Subsequently, the terminal receives data of the PPDU on the basis of the U-SIG field and the EHT-SIG field.
